A new study suggests epigenetic changes, alterations in gene activity without DNA code changes, may increase PCOS risk and be inherited. Researchers examined egg cells and embryos from women with and without PCOS, finding widespread disruptions in key genes and epigenetic markers in those with PCOS. These disruptions, potentially passed from mother to embryo, could lead to preventative IVF interventions, although further research, including mouse studies, is needed to confirm safety and efficacy in offspring.
